>I wonder if adding gravel/rocks helps prevent heave?
Just speculation on my part, but I would guess that rocky soil might help
prevent heave in two ways:
1. As plants send roots down under rocks, the rocks help keep the roots
well anchored.
2. Rocks and gravel in the soil should help maintain steadier soil
temps, which in turn should minimize the thaw/freeze cycles that cause
heaving.
Sounds reasonable to me, anyway.
